Vailankanni is the site of Roman Catholic Basilica of Our Lady of Good Health and its related sacred sites. This is an important place for the Christians and a large number of them come here to visit this sacred place. The structure is beautiful. It was elevated to the status of basilica during the year 1962 when Pope visited this place. There is an annual festival conducted here on 8 September, on the day of Mary’s birth. During that period thousands of pilgrims come here by walking all the way from Chennai or any other place. The atmosphere is quite amazing and it appeals to the people of all religions. During the tsunami of 2004, the place suffered a huge blow. There were many pilgrims here at that time when the tsunami struck. At least 2000 people lost their lives during this tragedy. A number of shops and houses were washed away due to that. But the church remained untouched.
